Applied, thanks. Please provide a Changelog next time, otherwise it's
hard to guess what you actually changed.

BTW I noticed the xload defconfig does not build anymore with this patch
applied because the image gets too big. I searched for the reason at got
a step closer. The SDRAM sequencer code is compiled into the image
multiple times, one time for each board. The intention was that the
linker throws away the unused copies via -ffunction-section and
--gc-sections. Unfortunately this does not work because the functions in
the different copies all end up with the same name. So for example we
have mem_precharge_and_activate() three times in the image. Only one
version is used, but the others can't be thrown away because they are in
the same section.

I hope we can solve this, otherwise we have to split the xloader
defconfigs into multiple configs.
